[0026] As a technical optimization scheme of the present invention, a pressing plate 405 is fixedly connected to the bottom of the connecting rod 403, and the pressing plate 405 is perpendicular to the connecting rod 403. When it is necessary to adjust the angle of the second hydraulic rod 9 according to the drilling angle, by pressing the pressing plate 405, when the pressing plate 405 moves downward, it drives the connecting rod 403 to slide. The connecting rod 403 drives the rack 402 to no longer mesh with the toothed ring 401. At the same time, the rack 402 causes the spring 404 to contract. When they are no longer meshed, the rotating shaft 7 and the mounting seat 3 are driven to rotate by the connecting block 8. When the rotating shaft 7 rotates, the pointer 15 and the scale bar 14 can be observed to observe the rotation angle of the rotating shaft 7. At the same time, when it rotates to a certain angle, the pressing plate 405 is released, so that the rack 402 moves upward under the action of the spring 404 to mesh with the toothed ring 401. At this time, the fixing of the toothed ring 401 and the rotating shaft 7 is completed. By meshing the rack 402 with the toothed ring 401, it is convenient to fix the rotated second hydraulic rod 9. When installing the bolt, the operator does not need to keep holding the handle 13 all the time, which improves the operation flexibility.
[0027] As a technical optimization solution of the present utility model, a fixing structure 5 is provided in the mounting base 3. The fixing structure 5 includes a fixing block 501 slidably connected to the mounting base 3. The fixing block 501 abuts against the connecting rod 403. A first lead screw 502 is rotatably connected in the mounting base 3. The fixing block 501 is threadedly connected to the first lead screw 502. A guide rod 503 is fixedly connected in the mounting base 3. The fixing block 501 is slidably connected to the guide rod 503. A first rotating rod 504 is fixedly connected to the first lead screw 502. The cross section of the fixing block 501 is in a "concave" shape structure. After the connecting rod 403 slides upward, the first lead screw 502 can be driven to rotate through the first rotating rod 504. When the first lead screw 502 rotates, the fixing block 501 is threadedly driven to move towards the connecting rod 403, so that the fixing block 501 fixes the connecting rod 403. By fixing the connecting rod 403 with the fixing block 501, the stability of the connecting rod 403 is improved. At the same time, when the fixing block 501 slides, it slides more smoothly through the guide rod 503.
[0028] As a technical optimization solution of the present utility model, an installation structure 6 is provided on the base 1. The installation structure 6 includes two installation rods 601 fixedly connected to the base 1. A fall-prevention frame 602 is fixedly connected between the two installation rods 601. The first hydraulic rod 2 is slidably connected to the fall-prevention frame 602. Two clamping blocks 603 are slidably connected in the fall-prevention frame 602. The clamping blocks 603 are in contact with the first hydraulic rod 2. A second lead screw 604 is rotatably connected in the fall-prevention frame 602. The clamping blocks 603 are threadedly connected to the second lead screw 604. The thread directions at both ends of the second lead screw 604 are opposite. A second rotating rod 605 is fixedly connected to the second lead screw 604. A guide shaft 606 is fixedly connected in the fall-prevention frame 602. The clamping blocks 603 are slidably connected to the guide shaft 606. A positioning column 607 is fixedly connected to the fall-prevention frame 602. A positioning sleeve 608 is fixedly connected to the side wall of the first hydraulic rod 2. The positioning column 607 is inserted into the positioning sleeve 608. The left end of the second hydraulic rod 9 is fixedly connected with a connecting sleeve 12. A handle 13 is fixedly connected in the connecting sleeve 12. A guide post 11 is fixedly connected to the left side of the mounting plate 10. The guide post 11 is slidably connected to the connecting block 8. When the first hydraulic rod 2 is installed on the base 1, the first hydraulic rod 2 can be passed through the fall-prevention frame 602, and the positioning sleeve 608 is inserted into the positioning column 607. By inserting the positioning sleeve 608 into the positioning column 607, the rotation of the first hydraulic rod 2 is avoided, and the setting of the fall-prevention frame 602 can prevent the first hydraulic rod 2 from tipping over during installation. At this time, the second lead screw 604 is rotated by the second rotating rod 605. When the second lead screw 604 rotates, the two clamping blocks 603 are threadedly driven to slide towards each other. When the clamping blocks 603 slide, they slide more smoothly through the guide shaft 606, so that the two clamping blocks 603 fix the first hydraulic rod 2. By fixing the first hydraulic rod 2 with the two clamping blocks 603, the stability during the installation of the anchor rod is improved.
[0029] As a technical optimization solution of the present utility model, a pointer 15 is fixedly connected to the rotating shaft 7. A scale bar 14 cooperating with the pointer 15 is provided on the mounting seat 3. When the rotating shaft 7 rotates, the pointer 15 and the scale bar 14 can be observed to observe the rotation angle of the rotating shaft 7.
[0030] When the utility model is in use, when it is necessary to adjust the angle of the second hydraulic rod 9 according to the drilling angle, by pressing the pressing plate 405, when the pressing plate 405 moves downward, it drives the connecting rod 403 to slide. The connecting rod 403 will drive the rack 402 to no longer engage with the toothed ring 401. At the same time, the rack 402 causes the spring 404 to contract. After the disengagement, the connecting block 8 drives the rotating shaft 7 and the mounting seat 3 to rotate. When the rotating shaft 7 rotates, the pointer 15 and the scale bar 14 can be observed to observe the rotation angle of the rotating shaft 7. At the same time, when it rotates to a certain angle, release the pressing plate 405, so that the rack 402 moves upward under the action of the spring 404 to engage with the toothed ring 401. At this time, the fixation of the toothed ring 401 and the rotating shaft 7 is completed. Through the engagement of the rack 402 and the toothed ring 401, it is convenient to fix the rotated second hydraulic rod 9. When installing the anchor rod, the operator does not need to keep holding the handle 13 all the time, which improves the operation flexibility. After the connecting rod 403 slides upward, the first lead screw 502 can be driven to rotate by the first rotating rod 504. When the first lead screw 502 rotates, the fixing block 501 is driven by the thread to move towards the connecting rod 403, so that the fixing block 501 fixes the connecting rod 403. By fixing the connecting rod 403 with the fixing block 501, the stability of the connecting rod 403 is improved. At the same time, when the fixing block 501 slides, it slides more smoothly through the guide rod 503. At this time, the drill rod can be installed in the drill 16, and the drill rod is used to drill the ore wall. By starting the second hydraulic rod 9, the second hydraulic rod 9 drives the drill 16 to move through the mounting plate 10. The mounting plate 10 drives the guide post 11 and the connecting block 8 to slide. The setting of the guide post 11 makes the mounting plate 10 move more smoothly. After the drilling is completed, take out the drill rod, insert the injection anchor into the joint of the drill 16, screw the locking nut onto the anchor rod to be installed and insert it into the injection anchor, put the resin cartridge into the hole, and use the anchor rod machine to send the resin cartridge and the anchor rod to the bottom of the hole. At this time, the installation of the anchor rod is completed. When installing between the first hydraulic rod 2 and the base 1, the first hydraulic rod 2 can be passed through the anti-toppling frame 602, and the positioning sleeve 608 is inserted into the positioning column 607. By inserting the positioning sleeve 608 into the positioning column 607, the rotation of the first hydraulic rod 2 is avoided, and the setting of the anti-toppling frame 602 can prevent the first hydraulic rod 2 from toppling during installation. At this time, the second lead screw 604 is rotated by the second rotating rod 605. When the second lead screw 604 rotates, the two clamping blocks 603 are driven by the thread to slide towards each other. When the clamping blocks 603 slide, they slide more smoothly through the guide shaft 606, so that the two clamping blocks 603 fix the first hydraulic rod 2. By fixing the first hydraulic rod 2 with the two clamping blocks 603, the stability during the installation of the anchor rod is improved.
